Normally one up day wouldn't constitute a trend but in the case of the BDI just one up day preceeded by one down day heavily favors an up trend. It's hard to read the BDI because the long term trend is obviously up. Consequently, one would normally expect that the odds of an up day following just one down day would be skewed for another up day. But just looking at history the odds that the BDI will be up both a week from now and a month from now should lead lillydick to be a less frequent visitor of this board.
On the other hand, it was HST that said there are lies, damn lies and statistics.
